Whilst putting together my kindling bags for our wood stove, I paused to appreciate how beautiful pine resin looks when held up to the light - the amber tinge is exquisite. The amber we prize in jewelry is actually fossilized resin from coniferous trees.
Resin and pitch come from coniferous trees, and is NOT water soluble; gum is found in deciduous trees, and IS water soluble. This distinction was new to me - I'd been using the word gum for all the pine residue stuck to my shoes, hands, outdoor laundry items, and deck all along.
